Qt官方示例-枚举器

❝该示例演示如何显示系统中串行设备的信息。 ❞

  此GUI示例在类QSerialPortInfo中提供有关小部件中的串行端口的信息。要获取有关可用端口的信息,请使用静态方法availablePorts()

  示例源码:

#include <QLabel>  #include <QScrollArea>  #include <QSerialPortInfo>  #include <QVBoxLayout>  #include <QWidget>    int main(int argc, char *argv[])  {      QApplication a(argc, argv);        auto layout = new QVBoxLayout;        const auto infos = QSerialPortInfo::availablePorts();      for (const QSerialPortInfo &info : infos) {          QString s = QObject::tr("Port: ") + info.portName() + "n"                      + QObject::tr("Location: ") + info.systemLocation() + "n"                      + QObject::tr("Description: ") + info.description() + "n"                      + QObject::tr("Manufacturer: ") + info.manufacturer() + "n"                      + QObject::tr("Serial number: ") + info.serialNumber() + "n"                      + QObject::tr("Vendor Identifier: ") + (info.hasVendorIdentifier() ? QString::number(info.vendorIdentifier(), 16) : QString()) + "n"                      + QObject::tr("Product Identifier: ") + (info.hasProductIdentifier() ? QString::number(info.productIdentifier(), 16) : QString()) + "n"                      + QObject::tr("Busy: ") + (info.isBusy() ? QObject::tr("Yes") : QObject::tr("No")) + "n";            auto label = new QLabel(s);          layout->addWidget(label);      }        auto workPage = new QWidget;      workPage->setLayout(layout);        QScrollArea area;      area.setWindowTitle(QObject::tr("Info about all available serial ports."));      area.setWidget(workPage);      area.show();        return a.exec();  }
